Standard Test Method for Laboratory Evaluation of Wood for Resistance to Subterranean Termites
ABSTRACT
This test method covers the laboratory evaluation of treated or untreated cellulosic material for its resistance to subterranean termites. This test should be considered as a screening test for treated material and further evaluation by field methods is required. Different kinds of equipment and materials to be used in the evaluation of the cellulosic material include containers, glass or clean plastic, tray, enamel, stainless steel, paper towels, and volatile chemicals. Southern yellow pine (SYP) sapwood with no visible defects and smoothed surfaces shall be evaluated by using reagents like benzalkonium chloride solution and distilled water. Other wood species may be used, but in each separate test using other species as the major test wood, five SYP sapwood blocks should be used as additional controls to permit the correlation of test results among laboratories. A block evaluation with corresponding rating system shall be performed by visualization method.
SCOPE
1.1 This test method covers the laboratory evaluation of treated or untreated wood for its resistance to subterranean termites. This test is considered as a screening test for treated material and further evaluation by field methods is required.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (Warning—See 7.1.4.)
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1.2 No-choice test—No-choice data-termites termites are presented with a singular choice and mass loss indicates ability of the
insect to consume the material. In no-choice data,tests, mortality data is needed to determine dose mortality based on consumption
of the test material, which is often treated with suspected insecticidal compounds.
